Joe, I can't help you with the tunes (though I can probably still sing the chorus of If I Were a Blackbird -- haven't heard it in a dozen years or so), but if you're learning to play the whistle you should check out a little booklet that I think is called the Irish Tinwhistle Tutor. Yes, I know, you said Scot, not Irish, but it's a helpful book all the same. Damned if I can remember the author's name, though I remember he was from Pittsburgh and I remember I heard him and his band play at the Philadelphia Highland Games in 1982 or so. I probably still have the book buried at home somewhere, and if I remember to look for it I'll post the correct title and author. Check a good folk music store or catalog. I love the whistle part on Blackbird. Wish I had taken my own advice and learned to play!

Aloha,
